Flatworm investation! PLZ HELP

[Tajjo]

I got home and my brother camo over and noticed them on that sand and on one isolated rock. He told me i have a problem i cant find anything in these forums on flatworms. What can i do? What will they do to my tank? Any info on them will help or if you know a good link, i need a solution first. Thanks

Try searching a little harder if you can't find anything. Treatment depends on the type of flatworm. You can try Salifert Flatworm Exit.

i used flatwork exit and they always came back, then when i got a 6 line wrasse they seemed to dissapear but i never saw him peck at them... never had them since (but he jumped a long time ago so it might have just been naturally occuring)
